It's pretty simple. Rattle trap exhaust is now smooth reving, with zero loss of power after updated dyno. Only issue would be weight, pretty heavy part to add in. One of the ideas behind this Hummer H3 was to reduce weight and all lite weight exhaust just got killed back to stock weight with this installed.

I only have an inline 5 cylinder egine so I wanted good performance,sound and better fuel economy. Thats what I got with the super 10. It added a better sound and tone to the inline 5.

Flowmaster mufflers have always been quality, but most often more than I wanted to spend. When I finally bit the bullet and bought one, it exceeded my expectations. It has a nice deep rumble that is not overly loud or offensive but about as loud as I want it to be. Sounds perfect for my straight 6 cylinder jeep.
